Assembly for pulling a line

ABSTRACT

The assembly comprises a rotatably mounted capstan member, a pulley member having an annular groove and a line guide means including a gate portion to direct the movement of the line from the capstan member onto the pulley member. The pulley member is mounted to rotate with the capstan member. The line guide means is disposed in fixed relationship with respect to the capstan and pulley members. The assembly of this invention may be used in combination with a power source to form a line pulling device.



1. An assembly for pulling a line comprising: a. a capstan member and apulley member rotatably mounted around a stationary center post, b. saidpulley member having an annular groove and mounted to rotate with saidcapstan member, and c. line guide means including a gate portion todirect the movement of the line from the capstan member onto said pulleymember, d. said line guide means being disposed in fixed relationshipwith respect to the capstan and pulley members, e. the gate portionincludes a disk member disposed between the rotatably mounted capstanmember and a pulley member, and f. the line guide means includes abracket portion extending from the disk member to the center post to fixthe position of the disk member with respect to the rotatable capstanand pulley members.
 2. In a device wherein a power source is operativelyconnected to a mechanical combination for pulling a line, saidmechanical combination comprising: a. a capstan member and a pulleymember rotatably mouNted around a stationary center post, b. said pulleymember having an annular groove and mounted to rotate with said capstanmember, and c. line guide means including a gate portion to cause theline to move from the capstan onto said pulley member, d. said lineguide means being disposed in fixed relationship with respect to thecapstan and pulley members, e. said pulley member including a pluralityof ribs and troughs disposed transversely to the circumference of theannular groove and at regular intervals along the surface thereof, f.said gate portion includes a disk member disposed between the rotatablymounted capstan member and pulley member, g. at least a section of thedisk member extends outwardly from the periphery of the capstan andpulley members and has an opening therein located to direct movement ofthe line from the capstan member to the pulley member, h. said lineguide means includes a bracket portion extending from the disk member tothe stationary center post to fix the position of the disk member withrespect to the rotatable capstan and pulley members.
 3. A pulleyassembly for pulling a line comprising; a. a rotatably mounted capstanmember, b. a pulley member having an annular groove and mounted torotate with said capstan member, and c. line guide means including adisk member fixedly disposed between the rotatably mounted capstanmember and pulley member, d. at least a section of said disk memberextending outwardly beyond the peripheries of the capstan and pulleymembers and having an opening through which the line moves onto thepulley member after it leaves the capstan member.
 4. An assembly forpulling a line comprising: a. a capstan member and a pulley member whichare mounted to rotate about a common axis of rotation, b. the pulleymember having an annular groove and being adapted to rotate in unisonwith said capstan member, and c. line guide means disposed in fixedrelationship with respect to the capstan member and the pulley member,d. said line guide means including a gate portion to direct the movementof the line from the capstan member onto said pulley member, e. saidgate portion extending in a direction transverse to the periphery of thecapstan member and the pulley member and along which gate portion theline moves as it winds directly onto the pulley member after it leavesthe capstan member.
 5. An assembly as defined in claim 4 wherein saidgate portion includes an opening through which the line moves as itwinds onto the pulley member after it leaves the capstan member.
 6. Anassembly as defined in claim 4 wherein said gate portion includes twoguiding surfaces between which the line moves as it winds onto thepulley member after it leaves the capstan member.
 7. An assembly asdefined in claim 4 wherein the line guide means includes a means todisengage the line from the annular groove of the pulley member afterthe line has moved from the capstan member to the pulley member.
 8. Anassembly as defined in claim 4 wherein the pulley member includes meansdisposed within the annular groove to enhance the gripping action on theline.
 9. An assembly as defined in claim 4 wherein a plurality of ribsand troughs is disposed transversally to the circumference of theannular groove and at regular intervals along the surface thereof.
